Abstract: The present disclosure relates to reference signal design methods and devices. In one example method, a first communication device obtains at least one sequence from a subset of sequences in a set of sequences and obtains at least one reference signal based on the obtained at least one sequence. The sequence is phase rotated during its generation, phase rotated in the frequency domain, or cyclically shifted in the time domain based on a constant value Δq. The first communication device transmits the reference signal to a second communication device.

Abstract: Methods and nodes, for assignment of uplink control channel resources for providing HARQ feedback for data transmitted on a downlink data channel associated with a downlink control channel. The downlink control channel comprises at least a set of downlink control channel resources, which is configurable over a subset of available time frequency resources. The method comprises dividing the set of downlink control channel resources into at least two subsets of references, comprising indices to the respective downlink control channel resources. Also, the method comprises defining, for each such subset of references, an associated subset of references comprising indices to unique uplink control channel resources. Furthermore, the method comprises associating each element in the subset of references with a subframe and an element in the subset of references. Additionally, the method further comprises transmitting data on the downlink data channel associated with the downlink control channel.

Abstract: A transmitting device and a receiving device are described for a wireless communication system. The transmitting device transmits one or more synchronization signals on a carrier to at least one receiving device. A frequency of a synchronization signal among the one or more synchronization signals is located on a first frequency raster, and a carrier frequency of the carrier is deployed on a second frequency raster. The frequencies of two different synchronization signals among the one or more synchronization signals are located on different frequency positions in the first raster. The transmitting device transmits an indication of the carrier frequency to the at least one receiving device. The indication comprises at least one integer number. The receiving device derives the carrier frequency based on the at least one integer number.

Abstract: A method is provided for arranging transmissions on a downlink carrier c, spanning a frequency range Fc, in a mobile radio communications system, wherein a bandwidth of Fc belongs to a set of predefined channel bandwidths in the communications system, and wherein the carrier c comprises a reference signal defined in the communications system. A configurable frequency range FRS comprising a set of time-frequency resources for comprising the reference signal of the carrier c is provided. Information associated with the configuration of the frequency range FRS is signaled to a receiver in the communications system, such that c can be deployed over a frequency range F smaller than Fc when the frequency range FRS is configured within F and any other transmissions on the carrier c are arranged to be within F.
